Pregnancy-specific beta 1-glycoprotein (SP1) levels were measured by nephelometry in sera from 107 women admitted to hospital because of vaginal bleeding in weeks 8 to 20 of pregnancy. The SP1 results were compared with those in single samples from 655 women and serial samples from 9 women with uncomplicated single pregnancies in the same period. The possibility of predicting the outcome of a pregnancy complicated by vaginal bleeding was calculated on the basis of the SP1 level on admission to hospital. In 65% a normal SP1 value predicted continuation of pregnancy, whereas a low SP1 value invariably predicted spontaneous abortion.
采用散射比浊法测定了107例因妊娠8至20周阴道出血而入院的孕妇血清中的妊娠特异性β1-糖蛋白（SP1）水平。将这些SP1检测结果与同期655例单胎妊娠未合并症孕妇的单次样本以及9例单胎妊娠未合并症孕妇的系列样本的检测结果进行了比较。根据入院时的SP1水平计算了预测妊娠合并阴道出血结局的可能性。在65%的病例中，SP1值正常预示妊娠将继续，而SP1值低则总是预示自然流产。
